FLUORESCENT IMAGING SYSTEM CAPABLE OF AUTOFOCUS USING FOCUS VARIABLE LENS AND FREQUENCY MODULATION OF LIGHT SOURCE

摘要

The present invention relates to a fluorescent imaging system capable of autofocus using a variable focus lens and capable of frequency modulation of a light source, comprising: a camera module having any one of a plurality of focal variable lenses; A camera control module for extracting the focus of the fluorescent image by moving the focal position of the focal variable lens up and down; And a light source control module for supplying a current corresponding to a periodic function having a constant frequency to the light source of the camera module to control the on-off function of the light source. According to the present invention as described above, it provides a fluorescent imaging system for scanning in the depth direction through the focus variable lens, and by supplying a current corresponding to the periodic function having a constant frequency to the light source (LED) to the on-off function of the light source By controlling it, it is possible to find and adjust the focal point accurately and quickly, to solve the heat problem of the light source by suppressing continuous heat generation, and to obtain a high contrast fluorescence image even under bright illumination of the operating room. Early diagnosis of the lesion is possible.
